/arte without arguments fails on bukkit and it's forks

[DanielSantin]

I'm trying to use paper 1.21.1, and it's giving the following error

Welp, that's weird. Arte should work without any commands, so, technically, it supports 1.21.1. I'll fix that afaic

[NikSneMC]

Does this bug occurs only when you run /arte without arguments?
